IMPROVEMENT IN GATES.

Specification forming part of Letiers'Patent-No. 57,963, dated September 11, 1866.

To all whom it may concern:

Be it known that I, STEPHEN PUFFER, of Oxford, in the county of Ohenango and State of New York, have invented certain new and useful Improvements in .G-ates for, Farming and other purposes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, which form a part of use of a large frictionroller moving on its] axis secured "to either of the stationary rear posts of I a gate, and providing each of said rear posts with a stationary guide-supporting bracket for guiding the gate and keeping the same equipoised when thrown open.

The bars A and uprights A comprise the frame-Work of the gate. The rear vertical posts, B B, are secured ,in the earth at such a distance apart from each otherin an oblique line to the line the gate'traverses as to admit of the free passage of thegate between them either way, the space between them being a little greater than the thickness of the gatebars A.

On the front face of upright B is secured the axis of a large friction-roller, G, the di nmeter of which relief is nearly equal to the space between the upper gate-bar A and the one next below, and it is so located on said post B as that, the lower edge of the upper gate-bar willbear thereon, thus acting as a way for the gate to move on.

To the inner front edge of post B and the outer rear edge of post B are secured the two guide bars D and B. 'These stationary guide bars have their upper front edges curved, as shown in Figs. 1 and 2, and are so located'on the posts in a line with each other as to receive the lower edge of the upper gate-bar and guide the same olf theroller 0 when the gate is swung open, after it has been moved back far enough to bring its center on a line with the roller 0. :Thus, when the gate has moved sufficiently far back to swing open, it clears the friction-roller G and is carried on to the guide-bars D and D, onwhich it rests equipoised.

' By the use of the guide-bars the strain consequent upon opening ors'winging around the gate is taken off the roller 0, as the two bars 1) Drec'eive and sustain the entire weight of the gate when opened.

l contemplate the use of a central bar, F, which may be secured as shown in Fig. 2 of the drawings, or in any other convenient manner. The rear end of this bar is provided with a friction-rollenc, whose diameter is equal to the space between the two central boards E of the panel adjacent to the postsB B.- This friction-roller, bytraversing the upper and lower edges of boards E, greatly diminishes the power required to move thegate backward and forward.

Any form of catch maybe used for securrail to its former position on the roller 0, on

which the gateimoves until closed.

Having. thusfully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is

1. Two or more stationary guide-supports for guiding. the gate from the friction-roller and sustaining, its weight'when opened, substantially in themanuer and for the purpose The foregoing specification of my improved herein set forth. gate signed by me this 17 th day of J uiy, A.
